P04 Motor (Auto-tuning)
The inverter automatically detects the motor parameters and saves them in its internal memory.
Basically, it is not necessary to perform tuning when a Fuji standard motor is used with a standard
connection with the inverter.
P04 = 1, 2, and 3 are only for asynchronous motors. P04 = 4 can be used for both types of motors.
For synchronous motors, the magnetic pole position offset tuning (L03) should be executed.

In any of the following cases, perform auto-tuning. This is because you may not obtain
the best performance under the PG vector control since the motor parameters are different
from that of Fuji standard motors.
• The motor to be driven is a non-Fuji motor or a non-standard motor.
• Cabling between the motor and the inverter is long. (Generally, 20 m (66 ft) or longer)
• A reactor is inserted between the motor and the inverter.
